In the present embodiment, a business form as a so-called karaoke box using a plurality of commanders 300 connected via a LAN has been described. However, in a night store such as a snack, one or more units are provided for one commander 300. A configuration in which a remote control device 200 is installed is employed.

  Next, the commander 300 as one configuration of the karaoke apparatus will be described in more detail. FIG. 2 is a diagram showing a block configuration of the commander 300 and its surroundings according to the embodiment of the present invention. 301 is a control unit, 302 is a communication unit, 303 is a front panel display unit, 304 is a display control unit, 305 is a storage unit, 306 is an input unit, 307 is a sound source unit, 308 is a mixing unit, 309 is an AD conversion unit, 401 Denotes an amplifier, 402 denotes a speaker, 403 denotes a microphone, and 404 denotes a display.

  Connected to the commander 300 are a display 404 as an image display device such as a CRT or TFT, an amplifier 401 as an audio amplifying device, and a microphone 403 as an audio input means. The performance signal of the karaoke musical piece in the commander 300 is sent to the amplifier 401, and a performance sound is obtained from the speaker 402. On the other hand, the lyrics video synchronized with the reproduction of the music is superimposed on the background video and output to the display 404 as an output video signal. The user sings using the microphone 403 in accordance with the performance sound and the lyrics video.

  The control unit 301 includes a temporary storage unit such as a CPU and a RAM, and controls the entire system in the commander 300. A storage unit 305 such as a hard disk stores music information, video information, various programs, and the like. The communication unit 302 uses a well-known standard wired LAN or the like, and can transmit and receive various control commands to and from the remote control device 200. In addition, various information such as music information and personal setting information can be transmitted to and received from the host device 100.

  The input unit 306 is a group of various switches provided on the front panel or the like, and can manually set various functions such as reserved music selection and pitch control. The display control unit 304 cooperates with the control unit 301 to create a lyric video based on the lyrics information in the music information stored in the storage unit 305.

In addition, the display control unit 304 performs display control for displaying various contents, advertisement information, and the like on the display 404.

  The sound source unit 307 functions as a reproducing unit that forms a musical tone signal based on performance information based on various standards such as MIDI, PCM, and MPEG. The sound source unit 307 can handle not only performance information composed of a single standard but also performance information composed of different standards. For example, the accompaniment can be played back by MIDI, and at the same time, the model song, back chorus, or recorded voice information can be played back by PCM or MPEG. The mixing unit 308 mixes the musical sound signal formed by the sound source unit 307 and the singing voice signal of the singer input from the microphone 403 with an appropriate balance. The mixed signal is output to the amplifier 401 and output from the speaker 402.

  In addition, in order to record a song, the song voice signal is also input to the AD conversion unit 309. The singing voice signal converted into the digital signal is voice-compressed into recorded voice information by the encoding process by the control unit 301 and stored in the storage unit 305. When only the singing voice signal is recorded, the singing can be reproduced by reproducing in synchronism with the performance information used at the time of recording at the sound source unit 307. Further, if the recorded voice information is created after mixing the singing voice signal and the performance sound, the singing can be reproduced by reproducing only the recorded voice information.

The main configuration of the commander 300 has been described above. However, a configuration may be adopted in which a communication unit that can transmit and receive IR signals is further provided to respond to control commands from a conventional remote control device that uses IR signals.

  Next, the remote controller 200 which is an embodiment as the specifying means of the present invention will be described. FIG. 3 shows the external appearance (front view) of the remote control device 200. A touch panel 207 is arranged in the center of the casing, and various displays are made to the user and the stylus 405 or a finger is brought into contact therewith. Accept user input. In the present embodiment, only the touch panel 207 is used. However, the present invention is not limited to this embodiment. For example, the touch panel 207 is configured to accept user input using a display unit and various keys or only various keys. A well-known remote control form can be employed.

  A fingerprint reading unit 203 as an authentication unit is provided on the upper right of the touch panel 207. A fingerprint is read by the user sliding his / her finger on the fingerprint reading unit 203. Features of the read fingerprint are extracted as appropriate by an algorithm and converted into fingerprint information. The authentication means is not limited to this form, and various biometric authentications and various types using IDs and passwords can be employed.

  FIG. 4 is a diagram showing a block configuration of the remote control device, in which 201 is a remote control control unit, 202 is a remote control communication unit, 203 is a fingerprint reading unit, 204 is a remote control storage unit, 205 is a remote control display unit, and 206 is a touch 1 shows a type sensor. The touch sensor 206 is transparent and is disposed on the surface of the remote control display unit 205, and configures the touch panel 207 together.

  The remote control control unit 201 controls the entire remote control device 200. The remote control storage unit 204 uses various memories such as a RAM and a hard disk, and stores a music list for music selection, personal setting information necessary for performing service processing, and the like.

  The touch sensor 206 enables an input operation by contact with a user's finger or stylus. In order to enable input by the touch sensor 206, the remote control display unit 205 is programmed to display a display image that is linked to control of the touch sensor 206. Note that the input means is not limited to the touch sensor 206, and mechanical input means such as a keyboard and cursor keys may be employed.

The remote control communication unit 202 performs wireless communication with the wireless access point 70 in accordance with, for example, a wireless LAN standard (IEEE802.11a / b / g). In this remote control communication unit 202, the remote control device 200 communicates with the commander 300 and the host device 100. The remote control communication unit 202 can also be realized by, for example, the Bluetooth standard (registered trademark). In that case, the remote control device 200 and the commander 300 perform wireless communication by the communication unit of the same standard provided on the commander 300 side on the receiver side. Furthermore, the remote control device 200 communicates with the host device 100 via the commander 300.

  Various commands such as music designation from the remote control device 200 to the commander 300 are transmitted via the communication unit 202. That is, the remote control device 200 performs wireless communication with the wireless access point 70 arranged on the LAN. However, since the commander 300 and the remote control device 200 are associated in advance, the commander 300 sends various commands to itself. Can be determined.

The fingerprint reading unit 203 has a function of reading a fingerprint by the user pressing or sliding the surface with a finger. The read fingerprint is subjected to authentication processing with the host device 100, and a user who has succeeded in authentication can receive various services as a login user. Some users do not like fingerprint authentication as an authentication method for login. Therefore, in the karaoke system according to the present embodiment, authentication using the fingerprint reading unit 203, authentication by inputting a user ID from the touch panel 207, and a password can be selected.

  As mentioned above, although the hardware configuration in this karaoke apparatus was demonstrated, next, the singing practice function using these hardware configurations is demonstrated using figures.

  FIG. 5 is a flowchart showing a series of processes of the karaoke practice function. When the singing practice function is designated by the input means such as the touch panel 207, the singing practice is started (S100). The title screen in the singing practice mode is displayed on the display 404 as the display means on the commander 300 side, and prompts the user to select a song (S101). When the music specification is received from the remote controller 200, the sound source unit 307 reproduces the performance information of the music. On the other hand, when the designation to end the singing practice is accepted, the singing practice is finished and the normal karaoke mode is returned (S103).

  In S104, along with the reproduction of the performance information, the singer inputs the singing voice signal from the microphone and sings, but the recording processing of the singing voice signal from the microphone 403 is started simultaneously with the start of the reproduction of the performance information. The In this recording process, only the singing voice signal may be recorded to create the recorded voice information, or the recorded voice information may be created after mixing the singing voice signal and the performance sound based on the performance information. When reproducing a song based on the recorded voice information based only on the singing voice signal, the performance information and the recorded voice information may be started simultaneously. Since the singing voice signal is handled as a monaural signal, the capacity of the recorded voice information can be saved. On the other hand, when reproducing a song based on recorded voice information obtained by mixing a song voice signal and performance sound based on performance information, it is only necessary to reproduce the recorded voice information. In this case, since the performance sound as a stereo signal is recorded together, the capacity increases, but fast-forward and fast-reverse during reproduction can be easily performed. These are appropriately selected as necessary.

  During the reproduction of the performance information, the singer can check the degree of coincidence between the singer's singing and the melody of the music on the playback screen displayed on the display 404 (S105). FIG. 6 is a diagram showing the screen during reproduction, in which 501 indicates a scale display field, 502 indicates a scale line, 503 indicates a passage bar, 504 indicates a note mark, and 505 indicates lyrics. The singer can sing while watching the lyrics 505 displayed in synchronization with the reproduction of the performance information on the screen during reproduction. Although not shown in the figure, the display color of the lyrics 505 is changed to indicate the singing timing in synchronization with the reproduction of the performance information.

  In the scale display column 501, twelve scale lines 502 are displayed in parallel in the horizontal direction, and the 12 scales that are higher in scale are shown. A passing bar 503 is displayed at the center of the scale display column 501, and the singer can confirm the singing scale and the singing timing by the note mark 504 passing there.

  The musical note mark 504 is displayed based on the melody information included in the performance information and the singing scale based on the singing voice signal of the singer. The musical note mark 504 indicates the musical scale by the musical scale line 502 where it is located, and indicates the length of the sound by the length in the horizontal direction. ing. As the performance information is reproduced, the musical note mark 504 based on the melody information scrolls from the right to the left of the screen, and the point in time when it passes the passing bar 503 is the singing timing.

The display form of the note mark 504 that has passed through the passage bar 503 is changed based on the comparison with the singing scale based on the singing voice signal. When the melody information and the singing scale meet the matching condition, the melody information and the singing scale are changed to note marks in a white shape as shown in the figure. On the other hand, when the melody information and the singing scale do not meet the matching condition, the note mark 504 based on the melody information is maintained in the same display form as before the singing timing, and the note mark 504 based on the singing scale is newly displayed above and below it. Is done. In this case, the display form may be varied as shown in the figure to indicate whether the singing scale is higher or lower than the melody. Further, when there is no singing voice signal input, that is, when no singing is performed, only the note mark 504 based on the melody information remains without displaying the new note mark 504. Thus, in this embodiment, it will be compared with the singing voice for each note unit of the melody information, but it is not limited to this embodiment, and the comparison and display are performed in units smaller than the note. Also good.

  In addition, various forms of algorithms can be adopted as the matching conditions between the melody information and the singing scale. For example, if the singing scales match even once at the singing timing within the melody scale, it may be considered that they match, or may be considered that they match if they match for a predetermined time or more. The display of the screen during playback has been described above, but the comparison result between the melody information being played and the singing scale is stored in the temporary storage unit or the storage unit 305 in the control unit 301 as needed. It will be used for time series evaluation creation and review reproduction, which will be described later. Further, the comparison between the melody information and the singing voice signal is not limited to the comparison based on these scales, and for example, the singing timing and the magnitude of the singing voice may be used.

  When the performance information is reproduced to the end, or when the reproduction of the performance information is terminated by the user's reproduction termination instruction (S106), the recording process and the comparison process are also terminated, and whether or not the reproduction time has been performed for n seconds or more in S107. Determine whether. This determination takes into account that when the reproduction time is too short, the overall evaluation of the singing cannot be performed, and it does not make sense to manage information such as time-series evaluation. In this case, after displaying a message indicating that scoring is not possible on the display 404 in S108, the process returns to S101 to display a music selection waiting screen and waits for a user instruction.

  On the other hand, if the playback time is n seconds or more, the process proceeds to S108 and subsequent steps, and comprehensive evaluation is performed. First, in S109, a time series evaluation is created based on the comparison result between the melody information and the singing scale. FIG. 7 shows the data structure of this time series evaluation. The time series data is composed of an index and entity data. The index includes the song ID of the used performance information, the user ID in the case of the singing practice by the logged-in user by the authentication means, the comprehensive date and time of the practice of singing, the overall evaluation such as the match rate, and the like.

  The entity data is time-series information created based on the comparison result between the melody information and the singing scale. In this embodiment, the average of the comparison results in units of 5 seconds is described. Without being limited to this embodiment, the comparison result may be used as it is, or an average in an appropriate unit such as every measure unit of performance information may be adopted.

  In S110, the comprehensive evaluation screen A is displayed. FIG. 8 shows the comprehensive evaluation screen A. In the figure, 506 indicates an evaluation column by scale, 507 indicates a match rate, 508 indicates a comment column, and 509 indicates a switch. The scale-specific evaluation field 506 shows the number of note marks 504 corresponding to the comparison result between the melody information and the singing scale. The singer can check whether his / her singing tends to be higher or lower than the melody by referring to the scale-specific evaluation field 506. The match rate 507 is a percentage display displayed corresponding to the numerical value in the scale-by-scale evaluation column, and is a numerical value indicating the number of matches in the scale of the melody information that can be sung. This match rate 507 is used as an evaluation of the entire song, and is used as a comprehensive evaluation of time series evaluation and time series reference recording. In the comment field 508, comments corresponding to the numerical values of the scale-specific evaluation field 506 and the match rate 507 are displayed.

  Thus, on this comprehensive evaluation screen A, the user can grasp his / her singing evaluation numerically. The user who has finished the confirmation selects the switch 509 using a cursor key displayed on the touch panel 207 and proceeds to the next comprehensive evaluation screen B.

  On the comprehensive evaluation screen B, it is possible to perform a comparative display between the time series evaluation based on the singing performed this time and the time series reference record obtained from the host device 100. In S111, communication processing for obtaining this time-series reference record from the host device 100 is executed. FIG. 9 is a diagram for explaining this communication process in detail, and shows the exchange of information between the commander 300 and the host device 100.

  When the communication process is started (S200), first, the commander 300 transmits the time series evaluation created by the current singing practice to the host device 100 (S201). The host device 100 that has received the time series evaluation creates and manages a time series reference record used for later singing practice based on the received time series evaluation. In S203, when the user who is practicing singing is not a login user, the music ID of the music that has been practiced this time is transmitted to the host device 100, and the time-series reference recording related to the music is inquired (S204). . In this case, it is not possible to obtain its own time-series reference record, but it is possible to obtain a time-series reference record as statistical information of the music managed by the host device 100. On the other hand, in the case of a logged-in user, the user ID is transmitted in addition to the music ID, and an inquiry is made about the time series reference record for the music (S205). In this case, time series reference records as statistical information can be obtained together.

  In response to the inquiry from the commander 300, the host device 100 searches and extracts the time series reference record and transmits it to the commander 300 (S206). At that time, there may be a plurality of time-series reference records to be transmitted. FIG. 10 is a diagram showing the data structure of this time-series reference record, and is composed of an index and entity data as in the time-series evaluation. The host device creates a time series reference record based on one or more time series evaluations received from the commander 300. The index includes a music ID, a type, and various types of information for each type.

The time-series reference record is created based on one or a plurality of time-series evaluations regarding the same music piece, and some examples are given. For example, the time series reference record received from the commander 300 may be used as it is, and the user's past time series evaluation may be referred to. In this case, the user ID, recording date and time, comprehensive evaluation, etc. are stored as various types of information (when the type is individual 1 in the figure). In addition, an average of a plurality of time-series evaluations for the same user may be taken so that the user can refer to an average of past time-series evaluations. In this case, the user ID, the number of exercises, the average of the comprehensive evaluation, and the like are stored as various types of information (when the type is individual 2 in the figure). In addition, an average of a plurality of time-series evaluations may be taken regardless of the user, and a general practice situation regarding the music may be referred to (in the case where the type is by music). In addition, using multiple time series evaluations performed by the same user in the past, connecting the best time series evaluation for each part and creating a time series reference record, the best record in singing practice so far Virtual reference may be made.
It is an average of entity data, and the index stores the number of times of singing. Similar to the time series evaluation, the actual data is an average of the comparison results in units of 5 seconds and has contents corresponding to the index type.

When the logged-in user makes an inquiry in the communication process (S205), the commander 300 can obtain the time series reference records of all types by referring to the music ID. However, in the case of an inquiry that is not a logged-in user (S204), a time-series reference record for each music piece is ordered. By obtaining such various time-series reference records from the host device 100, the commander 300 displays both the time-series evaluation and the time-series reference record, and the user can display the progress of his / her singing and the others including others. It can be compared with the song average.

  In S <b> 112, display of the comprehensive evaluation screen B displaying the current time series evaluation and the time series reference record obtained from the host device 100 is executed. FIG. 11 is a diagram showing the comprehensive evaluation screen B, 510 is a time series evaluation column, 511 and 512 are switches. In the time series evaluation column 510, the current time series evaluation and the time series reference record obtained from the host device 100 are displayed together on the same time axis in the form of a line graph. In the figure, the time series evaluation of this time and the time series reference record based on the previous two time series evaluations performed the previous time are displayed together, and the user can check the progress of singing practice, You can visually check the parts you do not like. The time-series reference record to be displayed is not limited to this form. For example, the time-series reference record of a type such as the individual 2 and the music shown in FIG. 10 may be displayed together. In addition, a plurality of time-series reference records may be displayed so as to be switchable based on user designation. For example, it is conceivable that the recording can be switched to the past n recordings, the average recording of one's own singing practice, the recording with a high overall evaluation, the average recording of singing practice including others.
